A few weeks ago I purchased a Dlink DIR-655 router to upgrade my home
network to wireless-N.  Around the same time I began to configure a few
machines in my house to use SoftSqueeze and had upgraded SqueezeCenter
to version 7.  I also began using WPA2 for security.

Performance was terrible.  Music would cut out, the web interface was
terribly sluggish and I was nearing my wits end trying to make it run
right.  However there was a catch - for some reason I had no problems
streaming through my SSH tunnel across the internet.  SoftSqueeze ran
great at work and the web interface was snappy, it was just unusable at
home over the wireless LAN.

I had changed a good number of variables so troubleshooting was no fun.
I tried changing SqueezeCenter to the text only interface, turning off
security, etc.  After fiddling with multiple router settings I have
finally narrowed it down to the WISH & QoS features in the router. 
There are features that are designed to prioritize wireless & internet
traffic and they are turned on by default.  As soon as I disabled these
features performance skyrocketed!  There are no more delays and I can
stream to 3 separate SoftSqueeze clients as well as over my SSH tunnel
with no delay!

After reading about the WISH feature some more I think I can enable it
again with some SqueezeCenter specific ports and make it work, but for
now I am leaving it off.  I don't really think QoS is responsible but I
am leaving it off anyway as I don't have any need for it.

I just wanted to share this as I assume there are plenty of folks with
D-Link routers with these features and it was no fun troubleshooting. 
I don't know if my situation is unique based on my system
architecture/encryption/etc. but hopefully it can help someone out
there suffering.  ;)
